HAULAGE-CLIP.

the position of the back of the head of the lever and the wedge-like continuation when the handle is raised to the full extent. Fig.

3 is a view of the inner surface of the righthand shell. Fig. 4 is a separate view of the head and body of the lever. Fig. '5 is a corresponding plan. Fig. 6 is a vertical section through the shells on the line as w in Fig. 1 (looking in the direction of the arrowthe coupling being omitted), show-' ing an adjustable hall and cup device flush at both ends. Fig. 7 is a separate view of the adjustable device.

This clip comprises two rocking shells, a central adjustable device for loosely connecting the shells and a lever furnished with a trunnion-peg; the head of the lever working along inclines on the upper parts of the shells. The coupling for effecting attachment to the drawbar of the tub or wagon is secured to the clip by a pin and split cotter.

The adjustable devices generally used are claimed in the specification to my United States Letters Patent No. 728421, granted May 19, 1903; the special hooked spring for holding open the jaws to facilitate the placing of the clip over the rope being claimed in the specification to my United States Letters Patent No. 941049, granted Nov. 23, 1909.

After the clip has been caused to grip the rope by the depression of the handle of the lever, the head of the lever arrives against two stops at the ends of the inclines; the downward movement of the handle being thus limited. The exact height of the handle above the rope is of great importance. These two stops (by keeping the upper parts of the shells away from each other) interfere with the opening of the Specification of Letters Patent.

jaws to release the rope; and are therefore no longer than is absolutely necessary. l/Vhen worn, they are a source of trouble; and, further, the abutting edges on the head of the lever are sharp and tend to run harshly along the inclines. The inclines are now made without stops for the head of the lever; but stops extend laterally from the body of the lever and bed against the shells below the front projections. These stops, though large and strong, leave plenty of room for the catch that locks the lever. The back of the head of the lever corresponds in size and shape with the head of the superseded lever; but there is a wedgelike continuation that gives a smoother ac tion on the inclines. When the lever is in its lowest position, this continuation does not touch the shells.

The adjustable device is reversible, so that,

when the curve-rollers are all on one side of the rope, the flush end of that device can be on the same side. Sometimes, however,there are curve-rollers on each side of the rope; and then an adjustable device flush at both ends is desirable. 'To obtain such a device, I dispense with the trunnioncollar. slightly alter the bolt and retain the trunnion-nut. The bearing surface on the head of the bolt is of ball shape to match a shallow cup formed on the boss of the shell. The bolt, which may have a square or hexagonal head, does not extend beyond the ribs of the shell; and has a round neck that turns in a hole in the boss. Near the cup the hole is round; but gradually becomes oval to permit the shell to rock. The threaded end of the bolt engages with the trunnion-nut mounted in the opposite shell.

R is the right-hand shell, looking in the direction in which the rope travels; L being the left-hand shell.

A is the central adjustable bolt having a bearing surface a of ball shape.

1" is the shallow cup formed on the boss of the shell R. V

B is the trunnion-nut into which the bolt A screws.

C is the lever with its large lateral stops C; C" being the handle.

0 is the trunnion-peg upon which the lever C is pivoted.

0' is the back of the head of the lever and 0 the wedge-like continuation.

The lever C is automatically locked by the catch D that turns on the joint-pin d.

cZ and cl are the front projections.

E is the coupling attached to the clip by the pin 6.

F and F are liners riveted in the jaws 7c and 7a.

m and m are holes in the shells R and L for the trunnion-peg 0.

N and N are the inclines (without stops) along which work the back 0 and continuation 0* of the head of the lever C.

P is the hooked spring; p and 10 being the recesses for the hooks.

I claim:

1. A haulage clip comprising a pair of rocking shells which have inclines without stops, a central adjustable device for connecting the shells consisting of a bolt having a bearing surface of ball shape that matches a corresponding cup formed on the boss of one of the shells, the bolt screwing into a trunnion-nut mounted in the opposite shell, and a lever pivoted to act between the inclines the lever being provided with stops extending laterally to bed against the fronts of the shells, substantially as described.

2. A haulage clip comprising a pair of rocking shells having inclines Without stops,

a central adjustable device connecting the shells and a lever pivoted to act between the inclines, the lever being provided with stops that extend laterally to bed against the fronts of the shells, substantially as described.

3. A haulage clip comprising a pair of rocking shells with inclines, a lever pivoted to act between the inclines, and for connecting the shells a bolt having a bearing surface of ball shape that matches a corresponding cup formed on the boss of one of the shells, the bolt screwing into a trunnion-nut mounted in the opposite shell, substantially as described. 7

4. In a haulage clip, the combination, with the rocking shells R and L which have inclines N and N, and the central bolt A that passes through a hole in one shell and screws into a trunnion-nut B mounted in the other shell, of the lever C pivoted 011 the trunnionpeg 0 to act between the inclines N and N and provided with stops C extending laterally to bed against the fronts of the shells R and L, substantially as set forth.
